This chipset is a Sound Blaster Pro 2. Yet another case of DOS drivers buried within a Windows executable. Is it a sin to sharpie on a legend? The jumpers are best left alone. Testing was done with ancient kernel version 3. SYS to get the sound initialized. Both 4 and 10 are supported by the hardware, albeit in a more roundabout way than the other IRQs.

Deleted one SIMM slot and the memory size jumper block. This one program is all you need to get the card initialized and working under plain DOS.

PC audio for luddites

I tested two of these that came in the as-is EBay lot. A second DMA channel is used only for full-duplex operation. Cleaning those cruddy contacts didn’t help. In the transition from ISA to PCI, and particularly with the introduction of AC’97audio chipset manufacturers took the opportunity to drop multi-clocking from their products. The MPU interrupt remains unknown and I can’t verify that this particular card even supports full duplex.

Solvusoft’s close relationship with Microsoft as a Gold Certified Partner enables us to provide best-in-class software solutions that are optimized for performance on Windows operating systems.


Here we go again. Utopia provided both 8 MiB and 16 MiB replacements. Maybe it’s a feature to avoid the old “stupid user set the volume to zero” problem. Yet another case of DOS drivers buried within a Windows executable.

Old Aztech cards like this one can be unambiguously identified by comparing the FCC-ID printed on the board against the list at ftp: Usually the complaint is “EMM incompatibility problem: I think it must need Windows 95 or DOS 6. The sound tests in DN3D setup sounded right but in the game itself the music was glitched.

ESS quit supporting their legacy products compaible time between and How is the Gold Competency Level Attained?

This was often done very poorly the Sound Cryetal Live! The wavetable synth works with aplaymidi —p Exiting and restarting it with no command-line switches seems to purge the problem, but it recurs.

The UltraSound base port is selected by jumpers, and there is a jumper to disable the game port. Solvusoft is recognized by Microsoft as a leading Independent Software Vendor, achieving the highest level of completence and excellence in software development.

I have tested examples of the latter two. This fix was applied in kernel 3.


W98SE comes with workable drivers for this comparible. To achieve a Gold competency level, Solvusoft goes through extensive independent analysis that looks for, amongst other qualities, a high level of software expertise, a successful customer service track record, and top-tier customer value.

ISA go Bragh™

It’s kind of funny that Advanced Gravis would be years ahead of their time on the other technical capabilities and yet didn’t think that a basic volume control was important. If you boot Windows and install this 3-floppy package available at ftp: It sometimes gets into a state that garbles OPL3 music and a power cycle is needed to reset it. The necessary drivers are now abandonware.

BAT suffices to initialize the card on each boot. I don’t know crywtal this is the correct name. It does provide bit fidelity without the need for WSS. Both documents are included in the PDF file here.
